WEFT-REPLENISHING LOOM.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed January 18, 1907. Serial No. 352,911.

To all whom it may concern:

Be it known that I, RANDOLPH CRoMPToN, a citizen of the United States, residing in Worcester, county of Worcester, and State of Massachusetts, have invented an Improvement in Weft-Replenishing Looms, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like arts.

This invention fias for its object the production of a novel filling-carrying magazine adapted to be used in that class of loom for supplying fresh filling-carriers in the path of movement of a pusher constituting part of any usual filling-carrier transferring mechanism to supply a shuttle with filling.

United States Patent No. 529,940, November 27th, 1894, shows a magazine of circular form comprising two disks each having a central hub mounted on a stud, the pusher and its carrying arm being located between said disks, the peripheries of said disks receiving one the butts of the filling-carriers and the other the ti s thereof, the magazine being capable of l i eing rotated intermittingly in the same direction for a like distance.

United States Patent No. 600,053, dated March 1, 1898, shows a cage com rising a hollow sleeve provided at one en with a circular head adapted to receive the tips of a series of bobbins, said head having a series of connected inwardly extended horizontally arranged arms supporting at their free ends an open-centered externally toothed ring provided at its periphery with notches to receive the heads of the filling-carriers supplied with filling differing in color or char acter, the hub of the cage being mounted to turn about a stud. The arm carrying the pusher of the transferring mechanism used in the loom shown in Patent No. 600,053, is represented as extended through the opencentered ring, into the center of the cage between said horizontally extended a'r'ms, the cage or magazine besides being capable of being moved in the same direction rotation after rotation, being also capable of being moved to-and-fro a number of times during each full rotation.

In the invention to be herein described the magazine will be provided with fillingcar-riers having filling differing in color or character, such as required in weaving colored goods wherein differences in color or figure are due to filling of different color or character.

My novel magazine, manually-controlled as to the time and extent of its movements comprises essentially, as I have chosen to illustrate the same herein, a circular rim having an inwardly extended radial arm shaped at its end to be sustained by a suitable bearing, said rim being adapted to receive and hold frictionally the butts or large ends of a series of bobbins or filling-carriers. Looking at the side of the rim of my novel magazine it presents an arc-shaped space inside the exterior of the rim, the space being terminated by the edges of the radial arm, the pusher being extended through said space that it may be placed in position to act on the filling-carriers sustained by the magazine, the extent to which said magazine may be rotated being limited bythe pusher or other suitable device meeting one or the other edge of said arm. The operator may by hand move said magazine in one or the other direction for less than a full rotation to place any filling-carrier sustained therein and having fillin of the desired color or character, in line with the path of movement of the pusher so that when said pusher is actuated after a movement of sald manually controlled device, any desired filling-carrier then in the path of movement of said pusher may bedischarged from the magazine into the shuttle in the usual shuttle-box at the end of the lay, the incoming fillingcarrier ejecting the fillingcarrier then in the shuttle through the underside of the shuttle and through a slot in the floor of the shuttle box, as commonly done.

The ma azine herein shown has a connected hand-w eel provided with means for holding the ends of the filling-threads. Herein I have combined with the magazine checking means to check and maintain the magazine in any position where it may be left by the operator prior to the action of the pusher. I have combined with the loom frame a trough or conductor into which is discharged the spent filling carriers as the cranks of the lay are moving in front of the lon itudinal axis of the crank shaft. I have a so combined with the manually-controlled device and MCI? 'hub B of said casting by a set-screw O, the .casting B having at its lower end a stud D forming a part thereof an operative member located at the end of the loom where is located the drop shuttle-boxes that said member may be moved whenever the weaver or operator, viewing a filling-carrier in a running shuttle in one of the cells of the drop shuttle box, considers that the filling-carrier should be replaced, the movement of said operative member placing the manually-eontrolled device in a position to effect the operation of the pusher at a subsequent pick or after the observed shuttle is thrown from its cell in the shuttle box across the race of the lay.

In case the operative member should be moved to effect a change of filling in the running shuttle at a subsequent pick and the shuttle box pattern surface should call immediately for a change of position of the shuttle box, then the operative member will be restored to its normal inoperative position by a restoring device moved in unison with the shuttle-boxes.

I have combined with the pusher releasing mechanism which is made operative as the pusher is moved to eject a bobbin from the magazine to release the operative member after a change of filling has been effected in the desired shuttle.

Figure 1 is a right hand end elevation of a loom with which I have embodied my improvements, the magazine supporting stud eing in section in the line 99, Fig. 9, the dotted lines showing in outline some devices shown fully in Fig. 6, and the lay in its forward position; Fig. 2 shows part of the manually-controlled means for calling into operation the pusher of the filling-carrier transferring means; Fig. 3 is a detail of the dagger; Fig. 4 is a detail showing one form of magazine checking means; Fig. 5 in front elevation shows part of the right hand end of the loom, the magazine being omitted, the figure showing the usher and the filling-carrier conductor, a Hing-carrier being shown by dotted lines in position to be struck by the pusher when moved; Fig. 6 in front elevation shows the o erative member and coacting parts that have applied to the left hand end of the loom where are located the dro shuttle boxes; Fig. 7 a sectional detail in t e line 66, Fig. 6; Fig. 8 on an enlarged scale shows my novel magazine in end view and looking at the same from the right, Fig. 1, the stud and part of the pusher being in section on the line 99, Fig. 9, and Fig. 9 is a partial section of the parts shown in Fig. 8 in a line parallel with the magazine sustaining stud.

The loom frame A, breast-beam A, stand B having bolted to it a casting B from which is extended a horizontal stud C secured in a fixed in position by a screw D, the stud having connected with it a spring I) one end of which acts against a laterally extended arm a, having a portion 0. provided with a finger a, said portion a and finger constituting part of the pusher or filling-carrier transferring mechanism adapted to act on whatever filling-carrier f is located directly below it when the said transferrer and pusher are actuated, the lay H, its single shuttle-box 11, the crank-shaft I1 connecting rod ll, canishaft and gears 11", H connecting the same, are and may be as usual in. weft-rep1enishing looms.

The series of drop shuttle-boxes H, Fig. 6, the guideways H attached to andv forming part of the lay at its end opposite that having the single box with which the pusher coacts, the shuttle S, but one being shown in Fig. 6 by full lines and by dotted lines in Fig. 1, the shuttle-box rod H, the box rod guide H the shuttle-box lever 11 connected with the box rod by a link H are and may be as commonly employed in looms of the type shown in United States patent granted to me No. 739,611, dated Sept. 22, 1903 and the shuttle-box lever in practice may be moved by any common or usual mechanism controlled by any usual or suitable pattern surface.

It will be understood that the shuttle has usual jaws that grasp the butt or ringed end of the filling-carrier, the shuttle being slotted at its under side to enable the filling-carrier to be ejected from said jaws through the bottom of the shuttle and thence out through the usual slot in the floor of the shuttle-box.

Referring now especially to features to be herein claimed, I have provided anovel 1n :1 gazine IE, it comprising a circular rim 0 having as shown a series of filling-carrier clamps (2 arranged in pairs, clamps substantially such as provided for in U. S. Patent No. 794,377, dated July 11, 1905, said clamps embracing the ringed buffs of the filling-carriersfhaving filling f. The rim of the magazine has an inwardly extended arm 0 presenting side edges 2, 3 that constitute the ends of the areshaped space 6 within the rim, the inner end of said arm having a hub 0*, that, as shown, fits the reduced inner end, see Fig. 9, of a quill or hollow sleeve 0 the outer end of said hub being shown as abutting one side of the hub 13*, the hub of the magazine being secured to said quill by a screw e extended through said hub and a hole in the quill, the inner reduced end of said screw entering an annular groove 0 in the stud C, so that said quill and magazine may be turned freely by the operator about said stud to place any filling-carrier of the series in the magazine under or in line with the pusher according to which particular filling-carrier of the series it is desired to eject from the magazine into the one or the other of the series of shuttles controlled by the drop shuttle-boxes, it being understood that the filling in said shuttles difiers in color or character, and that some of the filling-carriers in the magazine have filling of the same color or character.

In order to retain the magazine in any position in which it may be left by the operator, I have devised and combined therewith checking means, the same consisting, as herein shown in one good form, see Fig. 4, of a bolt h extended through a hole in a stand it, the enlarged inner end of the bolt engaging one or the other of a series of notches 10 in the rim e, the rim having a notch for each filling-carrier. The shank of the bolt is surrounded by a spring 7L2 contained in the stand it that acts normally to cause the head of the bolt to engage a notch and check the magazine in any position in which it may be turned by the weaver prior to the movement of the pusher. The outer end of the bolt has a collar h, and to withdraw the bolt when it is desired to move the magazine, I have provided a lever k mounted on a stud h see Fig. 4. In this way it will be readilyunderstood that the magazine may be checked and held frictionally in any position in which it may be turned by the weaver.

To the outer end of the quill e is secured by a screw F the hub of a hand-Wheel F provided at its periphery with a series of fillingholders shown as spring plates 12 held in place by screws 13. The outer end of the stud C is provided with a collar C held in place by a screw C The pusher arm a has a stud g on which is pivoted a dagger g forked at its end. The dagger normally sustained at its lower edge on a rest 9 is provided at its rear side with a shallow notch 40 and the free end of the dagger is guided in its movements by a slot in a plate m? having a boss m and secured to the loom and by a bolt The notch 40 is entered by a temporary sustaining device shown as a spring pressed pin m, Fig. 3, when the dagger is elevated, as will be described, into its operative position. The dagger lifting mechanism comprises a cam plate 10 secured to cam shaft H and provided with a cam groove p that receives a stud p at one end of a lever 10 mounted on a stud p of the loom end, the end of said lever nearest the breast beam having connected with it as shown in Fig. 1, a rod 1), the upper end of which is extended through a hole in the manually controlled device 19 Figs. 1 and 2, shown as a lever erected on a stud r of a bracket 1" connected with the loom end, a spring r connected with said loom end and with said device acting normally to retain said device in its inoperative dotted line position, Fig. 2, in contact with a stop 15 on said bracket, said rod 1) being reciprocated in said manually-controlled device as said cam plate p is rotated, it rising at every other beat of the lay and passing the inner side of said dagger without moving the same. When,

however, the operator desires to eject a filling carrier from the magazine into the shuttle open at its top and bottom and occupying a position in the single shuttle-box of the lay, having a slot in its floor as provided for in said patents, he will first turn the magazine by hand in one or the other direction to place under the pusher that fparticular one of the filling-carr1ers having illing of the color or character desired that it is wished to put into the shuttle in the single shuttle-box to replace a filling-carrier more or less exhausted, the same coming, it may be, from any cell of several cells of a series of drop shuttle-boxes, each shuttle containing filling of a particular color or character.

When the manually-controlled magazine has been placed in its desired position, the operator will move the manually-controlled device p into the full line position, Fig. 2, a ainst the stress of spring r to place the end 0% the rod 10 in line with the under side of the dagger g so that as the lay next comes forward with the shuttle in the single shuttlebox, the rod will lift the dagger into the path of movement of the bunter t carried by the lay, and the pin m will enter the notch 40, so that when said bunter in its forward movement meets the dagger, it will move the same to actuate the usher and eject from the magazine the fil ing-carrier then in line with the acting end of the pusher. As the bunter moves the dagger, as described, to move the pusher, the notch 40 in the dagger is carried eyond the in m and as the lay is moved away from the breast beam and the bunter retires from the dagger the latter drops by gravity onto the rest 9 while the spring D immediately raises the pusher into its normal inoperative position. By the term manually-controlled means I mean a device or devices, the movement of which de pends on the weaver or operator as distinguished from a device or devices moved wholly by the machine parts.

The lever p may be moved directly by the operator when standing at the end of the loom at which the magazine is located, but in order that the lever p forming part of the manually-controlled means may be moved by the operator standing at the end of the loom occupied by the drop shuttle boxes, I have provided an operative member or hand piece (1 Fig. 6, pivoted on a stud d of a bracket d fixed to the loom end, said hand piece having a stud d that may be engaged y a projection of a latch d pivoted at d and having at one end a foot d that is normally held by a spring d against a notched carria e d that is moved verticallyin a guideway d orming part of the bracket d riage d has as many notches as there are cells in the drop shuttle-box, a notch for each cell, and the carriage is moved up and down as the shuttle-box is moved in placing one or The caranother cell thereof at the level of the race of the lay. To move the carriage vertically, I have connected with a stud 7?. thereof, a link it, the lower end of which is attached to the outer end of a lever n pivoted at n the inner end of said lever being jointed. by a link a with the pin a that connects the link H with the shuttle box lever H The hand piece (Z is connected by a light rod or wire a extended across the loom with one end of the lever p the rod being extended through a tubular rock shaft a sustained in suitable bearings "a The rock shaft 71 has attached to it at its end next said pusher an arm 72/ that is held by a suitable spring in contact with the lower end of the pusher arm, see Figs. 1 and 5, while said rock shaft at its opposite end has a hub provided with a disengaging device shown as a finger a, said device when the pusher occupies its normal inoperative position crossing under thelat-ch (Z After moving the operative member (Z from its normal dotted position, Fig. 6, into its full line position which will be done manually to place the lever 12 in position to bring about the action of the pusher that it may be moved to eject a filling-carrier from the magazine into the shuttle in the single shuttle-box end of the lay, the shuttle coming, as herein shown, into said box from the top cell of the drop box, see Fig. 6, the latch (1 will engage the pin d and hold the hand lever and the lever p in their operative positions until the pusher is actuated, first lifting the dagger as before provided for. As the pusher is moved to eject afilling-carrier from the magazine into the shuttle then in the single box of the lay, the lower outer end of arm a will be moved to the left, Fig. l, and will turn the rock shaft n causing the finger a to rise, meet the inner end. of the latch d, and release the hand lever that it may be turned into its inoperative or dotted line position, Fig. 6, by the spring If, after the hand lever d which forms a part of the manually-controlled means, has been pulled prior to a pick of the shuttle which has a filling-carrier that it has been determined to change, the usual shuttle-box pattern surface, not shown, should call for a change of position of the drop shuttle box, the change of filling-carrier will not be made for the reason that the latch (3 will be automatically released whenever the shuttle boxes are shifted between the time that the hand lever (Z is changed to effect a change of filling-carrier and the time that the pusher is actuated to make such change. For illustration, let it be supposed thatthe weaver has just pulled the lever d to the left, Fig. 6, because he sees that the filling-carrier in the shuttle in the upper cell of the drop boxes should be changed as it arrives, after having been again struck by the usual picker in the single shuttle box at the opposite end of the esaeer lay. Let it be supposed that immediately after or as the lever d was pulled to the left, as shown in Fig. 6, the shuttle box was raised, it will be seen that the carriage (Z will be drawn down by the mechanism previously described and the rounded protuberance of the carriage in contact with the foot of the latch (1 will turn the latch and release the hand lever so that the spring T will act immediately to restore the lever 19 into its normal or inoperative position and the pusher will not be actuated. The operator having decided that the filling should be changed in the shuttle whose home is in the upper cell of the drop-box will watch when the box is again fully lowered and will again pull the lever, and this time if the drop-box stands in its lowest position for two or more picks the pusher will be moved to e'fi'ect a change of filling. It will be understood that the lever (2 will commonly be pulled while there is yet suflicient filling on a filling-carrier for quite a number of picks. That the filling-carriers ejected from the shuttle through the slot in the floor of the lay be conducted out of the lay, I have cut away the front side of the lay under said slotted floor to leave a space 0, see Fig. 5, and to the frame of the loom I attach a conductor 0 provided at its outer side with a deflector 0 the inner end of said conductor occupying a position substantially as shown in Fig. 1, so that its inner end stands in the space 0 of the lay under theiloor of the shuttle box when the lay arrives fully forward toward the breast beam, the position in which the pusher acts to eject a fillingcarrier from the magazine into the shuttle and discharge the filling-carrier then in the shuttle through the bottom of the shuttle and the slot in the floor of the lay. As a filling-carrier is discharged its tip end meets the deflector 0 which arrests the tip and permits the butt of the filling-carrier to lead in its travel over the conductor which is a matter of considerable advantage in the use of the loom.

This invention is not limited to the precise shape, construction or location of the checking means; nor is my invention to be limited in all instances to the employment with the magazine of the particular clamps shown for holding the filling-carrier, as l believe that I am the first to employ for a magazine a rim sustained by an inwardly extended arm revoluble about a stud and therefore I desire to claim broadly my novel magazine whatever means may be employed to hold the filling-carriers therein.

In practice, the loom will be stopped in usual manner by or through a filling-fork mechanism when the filling breaks or fails in the shed.

I further believe that I am the first to construct a magazine to sustain filling-carriers, said magazine being provided with looking means to check and lock and maintain said magazine in any position where it may be controlled magazine to sustain filling-carriers,
